Filter by:Venepuncture can be challenging, especially in patients with co-morbidities that predispose them to have inaccessible veins. Multiple unsuccessful venepuncture attempts compromise patient care. It causes pain, delays in obtaining blood samples for investigations and instituting intra-venous treatment. Venepuncture assistive devices (VAD) include ultrasonography, and devices that utilize infra-red or transillumination. These are expensive, not widely available, and have not been rigorously proven to be effective. We have previously performed a preliminary study using an ordinary pen-torch for transillumination showed promising results. 95% of patients with known difficult venous access required two or less attempts for successful cannulation. It costs 35 times cheaper compared to the cheapest VAD in the market. The concept is promising but the technique cumbersome. Building upon the concept of transillumination, the aim of this study is to develop an idiot-proof cost-effective pocket-sized VAD (TenTaTorch) to improve venepuncture success. A randomized controlled trial (RCT) will be conducted to determine its safety and efficacy. The TenTaTorch prototype will be modelled using Computer-Aided Design (Inventor®, Autodesk®, California, USA) and fabricated using 3D-printing, with silicon casting. Compared to existing VADs, TenTaTorch consists of finger-mounted LED light sources that allows greater manoeuvrability during transillumination. We include adult patients aged 21 to 100 with difficult venous access (history of ≥3 consecutive attempts required for successful cannulation during the current admission) requiring non-emergent venepuncture in the RCT. Each patient undergoes venepuncture over the upper-limb using one of the following: Conventional Venepuncture without aid (Control 1); Veinlite® EMS (TransLite®, Texas, USA) (Control 2), a commercial transillumination device; our device TenTaTorch (Experimental Group). Outcome measures include: successful cannulation within 2 attempts; duration of venepuncture; subjective user feedback. Fisher's exact and Kruskal-Wallis tests will be performed.
-Rivaroxaban is factor Xa inhibitor
To compare the impact on recurrence risk of adjuvant TAI and adjuvant TACE for patients with HCC and PVTT after hepatectomy.
As drug response is a complex trait in the majority of cases using an optimal starting dose for an individual may reduce the time taken to reach a stable INR, and reduce the risk of having either a high INR (with a risk of bleeding) or a low INR (with a risk of thrombosis)
According to the guidelines recommended, only a few new targeted therapy drugs treatment, such as Sorafenib, is proper. It's 3 year survival rate is only 8% or so. According to our previous study, patients with hepatic carcinoma without portal vein tumor thrombus backbone and the contralateral tumor thrombus applyed tumor excision, along with tumor thrombus, the 3 year survival rate can reach 39.9%, the 5-year survival rate can reach 22.7%, curative effect is obviously better.
After reports from observational studies suggesting an association between acutely ill medical patients and venous thromboembolism (VTE), interventional trials with anticoagulants drugs have demonstrated a significant reduction of VTE during and immediately after hospitalisation. Although several guidelines suggest the clinical relevance of reducing this outcome, there is a low tendency to use anticoagulants in patients hospitalised for acute medical illness. This observational multicentre study wants to evaluate the incidence of venous thrombo-embolism in acutely ill patients hospitalized in internal medicine wards.
The objective is to determine the incidence of thrombosis on central venous catheters in patients hospitalized in a surgical critical care unit, in the immediate postoperative period of urological or digestive carcinological surgery, and receiving parenteral nutrition.
This is an open label, multi-center, and randomized phase II trial designed to compare the safety and efficacy of direct oral anticoagulants and subcutaneous dalteparin in patients with acute venous thromboembolism and upper gastrointestinal, hepatobiliary, or pancreatic cancer, based on a group sequential design. Enrolled patients will be randomized in a 1:1 ratio. Patients will be stratified by performance status, type of cancer, chemotherapy and medical centers.
No randomized head-to-head comparison between the individual Non-vitamin K Antagonist Oral Anticoagulants (NOAC) exists. The DANNOAC-VTE study is a nationwide cluster randomized cross-over study comparing efficacy and safety of the four NOACs, edoxaban, apixaban, rivaroxaban and dabigatran for oral anticoagulation in venous thromboembolism across Danish hospitals.
Diagnostic errors have been reported frequently in patient with pulmonary embolism since symptoms are not specific. However, there is only scarce evidence that the delay associated with diagnostic errors may impact patient prognosis. The aim of this study is to determine the frequency of diagnostic errors and if they are associated with more severe pulmonary embolism in term of initial presentation and complications.
